While digging through the game files I found some new guns

Do you guys know if that SKS rifle 7.62 or not? I hope its not a one shot kill weapon

 

 

Not all 7.62 rounds are the same.  That's simply the diameter of the bullet at the widest point, but tells you nothing about the bullet's weight, length, shape, or the amount (and burn rate) of the powder behind it.  All rounds are also dependent on barrel length and twist rate.  To a certain degree, the longer the barrel, the more velocity the round will have before exiting the muzzle.

 

The M1 Garand/1903 Springfield uses a a 7.62 round, but it's a .30-06 or 7.62x63 cartridge.   Actual bullet weight varies from 150-220 grains in common ammunition.

The Mosin/SVT40/Dragunov uses a 7.62 round, but it's a 7.62x54R cartridge.  Actual bullet weight varies from 147-203 grains in common ammunition.

The .308 win is a 7.62 round very similar to the NATO 7.62x51 round.  Actual bullet weight varies from 150-180 grains in common ammunition.

The NATO 7.62 is a 7.62x51 round very similar to the .308 Win.  Actual bullet weight varies from 147-175 grains in common ammution.

The AK/SKS uses a 7.62 round, but it's the shorter 7.62x39R cartridge.  Actual bullet weight varries from 122-154 grains in common ammunition.

The new and speciailized AR15 .300 AAC Blackout (.300 BLK) uses a 7.62 round, but it's a 7.62x35 cartridge.  Actual bullet weight varies from 120-225 grains in common ammunition.

There are many more less common 7.62 cartridges than those listed above.

 

What's a grain?  A unit of mass measurement.  100 grains is about equal to 6.5 grams or 0.23 ounces.  The heavier the bullet, the slower it will fire from the same powder charge and barrel length, but it also requires a higher minimum twist rate of the barrel rifling to stabilize.  Also, heavier bullets are less affected by air resistance and wind, so they don't lose velocity as quickly as lighter bullets.  However, due to traveling slower initially, they have a more pronounced trajectory and more 'bullet drop' than lighter bullets.  One important factor in handguns and submachine guns is ensuring the bullet will not transition from supersonic to sub-sonic velocity during flight, as this drastically destabilizes the round.  Heavier rounds will be used in suppressed firearms to have an initial velocity just below supersonic (1,126 ft/sec at 68*F at sea level) so that they will remain stable without crossing that velocity level, but also to avoid the supersonic crack that all rounds fired above 1,126 ft/sec will have.  This is why supersonic .22LR ammo is significantly louder than subsonic .22LR ammo, which can be done with nearly the same powder charge just by changing the bullet weight from 38-40 grains to 60 grains.  It's also why non-suppressed .300 BLK uses a lighter bullet for long range accuracy at much higher muzzle velocity (125 grains at 2,200 ft/sec) while suppressed .300 BLK use heavier rounds at just below the speed of sound (220 grains at 1,000 ft/sec).

 

That said, those 6x 7.62 cartridges above all have drastically different cartridge sizes and weight, muzzle velocity, muzzle energy, and ballistics, along with other characteristics (like sound signature, effect of different barrel lengths and twist rates).  It's why I'd much prefer to be shot by an AK47 round (7.62x39 cartridge) than a M1 Garand (7.62x63 cartridge).  The M1 Garand's round has nearly twice the muzzle energy, and the heavier round will retain this higher energy for a longer range and be less affected by wind and air resistance.  This is why the AK/SKS round is never considered a 'sniper' cartridge even if you put a scope on the weapon.  The .30-06 is a heavier round that is also fired faster, so it also has a much flatter trajectory, making it easier to accurately hit the target at any range.  All these factors do not discuss the inherent accuracy resulting from the quality of the barrel, which is the most important factor in accuracy.  AK/SKS barrels are not known for accuracy.

I would think to be realistic the AK would have to be a bit less accurate than the M4 but do more damage, penetrate objects more.

 

good to see they have the skins in the game but that doesn't mean they are going to be in soon.

 

I wanna see the dragunov or SVD in the game :)

Yeah there are lots of skins around that aren't in game yet. These skins have been around for a while. I doubt we see them any time soon.

 

The 5.56 penetrates more than the 7.62 though. This is particularly true when firing military "green tip" M855 ammo. The M855 has a steel core penetrator.

[Celt (DayZ) 30]

full-auto rifle with detachable magazines using the same 7.62x39R ammo as the SKS (AK47).

It's an AK74 that they're adding, so it uses 5.45x39.

I've personally seen and shot steel core 7.62x39 rounds.. they exist as well.  Standard ball ammo in 5.56x45 and 7.62x39, the 5.56x45 will penetrate further at most ranges due to much higher velocity and smaller surface area.

I can attest to this. My local range was recently fucked over because some guy decided to sneak in some M855 ammo, which promptly blew through the backstop (indoor range), which I  believe is 1.5 inches of steel. So, yeah, M855's are nasty shit.

It penetrates certain things better, other things worse... there are different types of penetration. Animals, Kevlar, ceramics, steel, wood, brick, concrete, different bullets perform differently in different mediums.

True, in theory. I have never tested it in every medium lol. I have tested it on steel, kevlar, ballistic plates (sappi) and 5.56 penetrates more on all of them. Do you have anything specific that 7.62 penetrates more on? Would love to test it out.

 

(Keep in mind all those tests were done in a controlled environment using a universal receiver.)

Supposedly it performs better on a range of barriers such as windshields, walls and structures of different types, etc. Performance on windshields specifically was apparently one of the complaints about M855 which led to M855A1. Also more penetration in animals due to lack of fragmentation.

 

However the military steel-core 7.62x39 surplus was classified as an armor-piercing by the ATF and has been banned from import since 1994.

Yeah the windshield thing was true. I heard it had to do with the round being too fast :lol: . Isn't the 5.45 and 5.56 steel core ammo still legal? The ATF does dumb things sometimes lol.

Yes, they are still available for import. M855 is exempted on the grounds of "sporting purposes". The remaining steel-core 7.62x39 is still available for private sale, importation and FFL sales to non-FFLs are illegal. 7.62x51 is also considered a handgun cartridge by the ATF and 7.62x51 AP is also banned from import or FFL sales. They are just ignoring 5.45x39 and 7.62x54R for the time being, even though "pistols" are being produced chambered for all these cartridges.

Please tell me you're talking about 762x39, 7.62 NATO makes 5.56 look like paintballs in terms of stopping power and penetration

It depends on the bullet.

"The vast majority of everything we've got back from the field is positive," said Lt. Col. Jeffrey K. Woods, product manager, small caliber ammunition, during a "media day" at Aberdeen Proving Ground, Md.

A test fire an Aberdeen Proving Ground range pitted the M855A1 round against the M855 and the M80 in multiple weapons -- the two 5.56mm rounds were fired in both the M4 and the M16, and the 7.62 M80 round was fired in an M14 Enhanced Battle Rifle. All three rounds are use today.

In all test firings against a sheet of 3/8-inch mild steel plate at 300 meters, the M855A1 came out on top. The new round is also "superior to 7.62mm M80 against soft targets," Woods said."
